'SLIGING-MACHINE.

Specification of Letters Patent.

Patented Sept. 21, 1920.

Application filed March 18, 1919. Serial No. 283,411.

To allwhom it may concern:

I Be it known that I, WALTER CHANDLER KNAPP, a citizen of the UnitedStates, residing at Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements inSlicing-Machines; and I do declare the following to be a full, clear,and exact description of the same, taken in connection with theaccompanying drawings, forming a part of this specification.

My invention relates to slicing machines, more particularly to that kindof slicing machine employed for slicing bread and the like, in which thematerial being sliced is fed step by step to a revolving cutter orknife. The object of my invention is to provide a machine of this classwith means for saving the crumbs which are usually scattered on thefloor. A further object of my invention is to provide a chute at thelower side of the knife hood for directing the crumbs falling therefrominwardly and downwardly to a' receptacle provided therefor beneath themachine.

To these and other ends my invention resides in the arrangement andcombination of parts illustrated in the accompanying drawings and moreparticularly pointed out in the appended claims.

In the drawings:

Figure 1 is a side elevation of a slicing machine showing theapplication of my improvement, the front end of the machine being brokenaway, and

Fig. 2 is a rear end elevation of the same.

Similar reference numerals refer to the same parts in all the figures ofthe draw- Iify slicing machine comprises a frame 1 in which is rotatablymounted a shaft 2 having a knife 3 secured thereto at its rear end. Acollar 4 is secured to the shaft to engage the frame and constitutes athrust bearing for the shaft. The rear end frame member has arectangular opening 5 therein, through which the material to be slicedis fed to the knife which cooperates with the rear end of the frame toslice the material. A chute 6 is supported in the frame and serves tosupport the material, as it is fed to the knife. A pusher 7 is adaptedto have a step by step movement in the chute to move the material to theknife. If desired the pusher may be provided with a plurality of points8 adapted to positively engage the material to be sliced. A worm 9 isrotatively mounted in the frame beneath the chute, and is operativelyconnected with the pusher. Means, not shown herein, are provided forimparting a step by step rotary movement to the worm for moving thepusher forwardly step by step between successive strokes of the knife.If desired, a table or support 10 may be provided at the rear end of thechute 6 to catch and support the sliced material.

A hood or guard ll constructial of sheet metal. and of substantiallyinverted U shape is suitably secured to the rear end of the frame andincloses the knife. The hood comprises front and rear walls 12 and 13connected at their outer peripheries by the wall 14, and open at thelower ends as at 15. The walls 12 and 13 are cut away centrally toprovide a clearance for the material being sliced.

In practice it has been found that a large quantity of crumbs fall tothe table from between the chute 6 and the support 10 and also from thehood or guard 11 especially from the right hand side as viewed in Fig. 2of the drawings toward which the knife moves. These crumbs falling fromthe hood usually fall to the floor and are not only lost but cause anunsightly appearance. My invention consists in providing means forcatching the crumbs falling from the hood and directing them into areceptacle adapted to receive them and also the crumbs fall ing frombetween the chute 6 and the support 10. To this end I provide a. chuteor crumb catcher 16 substantially U shaped in cross section and adaptedto cooperate with the front, rear, and side walls of the hood andprojecting downwardly and inwardly to catch the crumbs falling from thehood and direct them to the receptacle 17 which may be provided toreceive them. The chute 16 may be made integral v. iththe hood 11 or ispreferably made separate therefrom and secured in position with itsupper and side edges in contact with the walls of the chute by anysuitable means, such as screws. While I show and describe only one chuteor crumb catcher 16 applied to that side of the hood toward which theknife moves it is to be understood that I do not desire to be limited tothe exact construction illustrated and described herein,

but that another chute 16 may be employed on the other side of the hoodif desirable Without departing from the spirit or scope of my invention.

Having described my invention What 1 claim and desire to secure byLetters Patent 1. In a slicing machine, the combination of a frame. aknife revolubly mounted therein, a chute for guiding the materiel to theknife, a support for the sliced material, a hood for protecting theknife, an a crumb chute cooperating With the hood and adapted to directcrumbs to a receptacle adapted to receive them.

2. In a slicin machine, the combination of a. frame, a knife revolublymounted therein, a hood for protecting the knife. and a crumb chutesecured to the Walls of the hood renews and adapted to direct crumbsdownwardly and inwardly to a point beneath the kngfc,

3. In a slicin mttchine, the combination of a, frame, a knife revolublymounted therein, a hood for protecting the knife, and a crumb chutecooperating with the front, rear, and side walls of the hood andprojecting inwardly to direct crumbs to a point beneath the knife.

4. In a slicing machine, the combination of a frame, a knife revolublymounted there in, a hood inolosing the knife and open at its lower end,and a crumb chute projecting inwardly and downwardly from theopen end ofthe hood and adapted to direct crumbs into a receptacle adapted toreceive them.
